Storm Preparedness: Keep Generators & Fuel Ready

When severe weather is in the forecast, most homeowners focus on stocking up on food, water, batteries, and other emergency supplies. Just as important, however, is making sure fuel-powered equipment is ready to perform when it is needed most. 

Portable generators, chainsaws, water pumps, and other outdoor fuel-powered equipment often become essential during storms. They help maintain power, clear debris, and protect property when conditions are at their worst. But these tools are frequently overlooked until the moment they are needed. 

Unfortunately, that is when problems tend to show up. 

Why Fuel Matters During Storm Season 

Fuel does not stay fresh forever. Over time, gasoline begins to degrade through oxidation, which can form gum and varnish inside fuel systems. These deposits may restrict fuel flow and make engines difficult to start. 

Ethanol-blended fuels can also absorb moisture from the air, increasing the risk of corrosion and fuel instability when equipment sits unused for long periods. 

If a generator or chainsaw fails during a power outage, it is often not a mechanical failure but a fuel-related issue that developed during storage. 

For homeowners looking for a broader storm readiness checklist that covers planning, supplies, and home preparation, see our guide: A New Homeowner’s Guide to Storm Preparedness. 

Prepare Equipment Before Storm Season 

The best time to prepare equipment is long before severe weather arrives. 

Before storm season, inspect any fuel-powered equipment you may rely on: 

• Portable generators  

• Chainsaws  

• Water pumps  

• Pressure washers  

• Lawn tractors or utility vehicles  

Start each machine and allow it to reach operating temperature. Listen for rough running, hesitation, or surging. These are early signs of fuel or maintenance issues that should be addressed before an emergency occurs. 

Check oil levels, inspect air filters, examine spark plugs, and look for signs of wear or cracking in fuel lines. Small maintenance issues are far easier to fix in advance than during a storm response. 

If fuel has been sitting in a tank or container for an extended period, replace it with fresh fuel before storage or use. Old fuel is one of the most common causes of poor performance in small engines. 

Keep Stored Fuel Fresh and Ready 

One of the most common mistakes homeowners make is waiting until a storm is approaching to buy fuel. 

During severe weather events, fuel shortages and long lines are common. Preparing ahead of time helps reduce stress and ensures equipment can be used immediately when needed. 

Fuel should always be stored in approved containers in a cool, dry, well-ventilated space away from ignition sources. Containers should be clearly labeled, and stored fuel should be rotated periodically so older fuel is used first. 

Proper storage alone helps, but fuel quality naturally declines over time. This is especially true in seasonal equipment that may sit unused for months at a time. 

STA-BIL Storage® Fuel Stabilizer helps keep gasoline fresh during storage by helping prevent fuel breakdown and reducing the formation of deposits that can affect engine performance. Treating fuel before storage helps ensure it remains ready when emergency equipment is needed. 

Maintenance for Storm Readiness 

 Portable generators are often the most important tool during a power outage, but they are also among the most neglected. 

When properly maintained, they provide critical backup power for refrigerators, sump pumps, lighting, medical devices, and communication equipment. When neglected, they are one of the most common points of failure during storms. 

To help ensure reliability: 

• Run the generator regularly  

• Test it under electrical load when possible  

• Check oil levels and replace as needed  

• Inspect spark plugs and air filters  

• Keep fresh, treated fuel on hand  

It is also important to verify extension cords and connections are in good condition, as damaged cords can create safety risks or reduce performance under load. 

Generators should always be operated outdoors in a well-ventilated area and never inside a home, garage, or enclosed space. Reviewing the owner’s manual before storm season helps ensure safe operation when conditions are stressful and time is limited. 

Be Ready for Cleanup 

Storm recovery often requires quick access to outdoor fuel-powered equipment. 

Chainsaws, trimmers, and similar tools are commonly used to clear fallen trees, remove debris, and restore access to property. In many cases, cleanup begins immediately after a storm passes, making reliability especially important. 

Before storm season, ensure: 

• Chains are sharpened and properly tensioned  

• Safety equipment such as gloves and eye protection is functional  

• Bar oil and replacement parts are available  

• Equipment starts and runs properly under load  

Taking time to prepare this equipment in advance reduces delays and helps make cleanup safer and more efficient. 

If fuel-related issues occur after long storage, STA-BIL Fast Fix® can help with rough running engines, and STA-BIL Start Your Engines!® can help with non-running engines. 

If problems persist, carburetor cleaning or replacement may be required to fully restore proper fuel flow and engine function. 

Be Ready Before You Need It 

Storms are unpredictable, but equipment readiness does not have to be. 

By maintaining fuel-powered equipment, storing fresh fuel properly, and testing generators regularly, homeowners can greatly improve reliability during severe weather events. Preparation is not only about avoiding problems, but also about reducing stress when conditions are already difficult. 

When equipment starts reliably, recovery becomes faster and safer. When it does not, small issues can quickly become major challenges. 

At STA-BIL®, we believe confidence during storm season starts long before the forecast changes. A little preparation today can help ensure your equipment is ready when it matters most. 

Frequently Asked Questions 

How long does gasoline last in outdoor power equipment? 

Gasoline typically begins to degrade in about 30 days under normal storage conditions. Using a fuel stabilizer and proper storage methods can extend usable life for several months depending on environment and handling. 

Do I need fuel stabilizer for storm season? 

Fuel stabilizer is recommended because it helps slow fuel breakdown and reduces the formation of deposits that can clog fuel systems. This improves starting reliability for stored generators and outdoor equipment. 

Why won’t my generator start after sitting unused? 

The most common cause is stale fuel that has broken down and created deposits in the fuel system. These deposits can restrict fuel flow and prevent proper ignition even if the engine is otherwise functional. 

Should I run my generator before storm season? 

Yes. Running your generator periodically confirms it is operating correctly, helps keep components lubricated, and allows you to identify maintenance issues before an emergency situation occurs. 

Can ethanol fuel damage small engines? 

Ethanol-blended fuel can absorb moisture over time, which may contribute to corrosion and fuel instability in small engines. This is especially problematic when equipment is stored for long periods without use.
